Abstract (en)
[origin: EP0651582A2] Device for transmitting television pictures in the form of transform coefficients and motion vectors. The motion vectors of a sub-picture are converted (20) into a series of difference vectors and a reference vector. Said series is subsequently applied to a variable-length encoder (22) which encodes a run of zero values and a subsequent non-zero value into a code word of variable length. The variable-length encoder may be the same as the encoder which encodes the coefficients. <IMAGE>
